You need to look closely with your hosting especially if you are a video blogger. Videos occupy lot of bandwidth and I’m sure you don’t what to see you blog with “Bandwidth exceeded” notice one day.
Hosting is the backbone of your blog or website. There are too many hosting providers these days and not all hosting providers provide what you really need. As mentioned above about video blogging, you need to churn all provided information about your prospect hosting.
The more capacity your server has, the better of course. Just read information including the FAQ for you to the have a better view on what will be the possible services you might be getting with that particular hosting package.
Unless you are one of those serious internet marketers, you will be forced to have you own dedicated server. This is expensive compared to other hosting packages. Choose the best that will suit you needs. You do not need that type of server yet, unless you need it now.
I would suggest you view and read some of the intricacies of web hosting first before getting one.
